Digg launches Stack and Swarm

The tools itself are funky and at the same time quite useful. I was among many users who actually discovered the Digg story about the official announcement through the visualization of it's growing importance. Kinda mind bending, especially if it's as hot as right now.

Another interesting part of the announcement is that they want to release an API to the visualization data "as the project matures". I could see this getting incorporated into many existing and yet-to-be-launched mashups.
